its highly relevant. a full bar of spells with 2sec gcd between them with 20-25cds on them allows one to usually always have a spell ready, or quickly have them ready. not to mention if you miss them or have full mcap and no agi THEN miss them? it comes down your cds till they come back up. would you rather have a slow bar todo damage or a fast one and a bit less vit? that's the point in having a choice of the two. now if you remove dr or reduce it, no one will ever go it again because its only so much to begin with.
I personally have no qualms about dr. Also you used the wrong variant to scale DR to. It reduces damage, which is linked to power, not vit. 27% DR on 300 power stat is 219
17% DR is 249 power.
7% DR is 279 power.
After that calc then you could multiply it by spell power and find your respective damage calculations. :)
edit: also cooldowns do have a decimal. I timed a specific spell to scale at 4.9, it showed 4 but when I ran the timer it was still closer to 5
